Joe Brice preaches about the importance of enthusiasm and passion in religion, contrasting the reserved nature often associated with piety to the fiery devotion seen in New Testament Christianity. He emphasizes how the early Christians, filled with the Holy Spirit at Pentecost, were transformed into bold and zealous followers of Christ, willing to be seen as fools for the sake of the Gospel. Brice highlights the necessity of being ablaze with the love of Jesus, as it is this fervor that drives true discipleship and the mission of the Church. He challenges believers to move from formalism to fervor, from duty to devotion, and from cold obedience to passionate righteousness, echoing the apostolic zeal that was disciplined and used for the purpose of love in the world.
